Designed primarily for use in the materials handling field as blowing seals or rotary feeders, a novel feature of these F Et R Valves has been the tapered rotor; this is readily adjustable, on site, to suit the particle size or to take up wear. The new 400 mm size, however, will be available with the option of a tapered closed-end rotor or a parallel open-ended rotor.

Another feature, said to be unique to this design, is that all solid bladed rotors will have a flexible end plate ring, which will give a peripheral seal even with a rotor/body clearance set as wide as 0.005 in.
The nose of the poppet will stop metal-to-metal, against the valve orifice under conditions of high back pressure. This eliminates oversqueeze and possible damage to the O-ring seal, and minimises any tendency for the valve to stick in the closed position.

The Capsulon range is based on an advanced design of vacuum gauge which combines electrical output and barometric compensation. Working parts in the gauges are isolated from sources of contamination and corrosion’ in the vacuum process. This gives them excellent reliability and long working life. Electrical output from the gauges can be used to drive remote meters or to operate a switching facility via a relay, and the Capsulon concept thus offers one of the lowest-cost and simplest methods available of automating vacuum processes.
